The promotion rules only apply to gschem; gnetlist treats all attributes as un-promoted regardless of the configuration settings. (I guess this should be documented somewhere.) If a component has an attribute with the same name as a symbol attribute, gnetlist uses that attribute. Otherwise, it uses the symbol's attribute. You can (almost) get the behavior you described by adding these lines to your gafrc file: (attribute-promotion "enabled") (promote-invisible "enabled") This will cause gschem to promote all attributes; further changes of existing symbol attributes won't affect the schematic. To un-set an attribute, set its value to "unknown". (This has some limitations, though, as John Doty pointed out.) Roland
